Project Focus: Safety New York City is aggressively pursuing its
“Vision Zero” initiative:
“Traffic Death and Injury on City streets is not acceptable”
Vision Zero Goal : to eliminate traffic deaths by 2024 CV technology is another potential tool for the Vision Zero
initiative.
The project will evaluate the safety benefits and challenges of implementing CV technology with a significant number of vehicles in the dense urban environment.

NYC Pilot Deployment – Users Summary
Project area: □ Manhattan Arterials (below 67th street) □ Manhattan “freeway” – FDR Drive □ Brooklyn (Flatbush Ave.)
Fleets will experience V2I applications where CV infrastructure is installed Fleets will experience V2V applications throughout the City City fleets (MTA, DOT, & Sanitation) return to “barn” daily Taxis – return to “barn” for shift changes
RSE Locations:
□ 8 on FDR, 38 on Flatbush, 204 Manhattan (Avenues), 40 Manhattan Cross-Town, 38 Other locations = ~ 320 (TBD)
14 U.S. Department of Transportation
NYC CV Challenges - Everywhere
Density of Roadside DSRC Transponders (RSE) □ ~76 M for short blocks □ ~200 M for the long blocks (between avenues)
DSRC only communications □ Need to develop applications for system operation and management
Bandwidth limitations of the wireless backhaul (RSE to TMC) Stakeholder privacy concerns vs. USDOT desire for broad evaluation data Stakeholder requirements to avoid distracting “cockpit” displays Ongoing maintenance and support (in-vehicle and infrastructure) of the large
scale deployment (10,000 Vehicles and ~320 RSEs)
SCMS* for all applications & DSRC Over-the-air (OTA) certificate distribution OTA DSRC data collection – bandwidth limited OTA DSRC software updates Location accuracy in the urban canyons (both relative V2V and absolute V2I)
DSRC – Nominal 300M

User Safety Needs
Need to “manage” speed (25 MPH city-wide except Fwy)
Need to reduce vehicle-to-vehicle crashes
Need to reduce pedestrian injuries
Need to reduce crashes & injuries at intersections
Need to reduce crashes involving buses Need to reduce the crashes of vehicles with infrastructure
□ Overheight, and restricted roadways
Need to inform drivers of serious incidents and major travel restrictions □ Evacuation, special event restrictions, detour □ Likely restricted by area and roadway
18 U.S. Department of Transportation
Other User Needs
Minimize introduction of additional driver distractions Ensure privacy for the drivers Minimize union concerns for fleet drivers – performance monitoring Manage CV applications for the changing (daily) traffic environment
Determine utility of CV BSM data for input to the City’s Adaptive Control System (MIM-ACDSS) Evaluate use of CV technology to reduce PED injuries Evaluate use of CV technology with Smartphone applications for
disabled pedestrians □ Notifications to Vehicles, Stakeholders: do NOT notify pedestrians
Needs for data to measure system performance Needs to manage the overall operational integrity of the system Data needs for the Independent Evaluator

The Approach
Focus on “proven” Safety Applications – rather than mobility □ BAA stressed that R&D has shown the benefits □ Pilot Deployment will evaluate the benefits on a larger scale –
dense urban situation Leverage “existing” safety applications – rather than “re-invent” Modify several existing applications to encourage speed compliance
□ Note that the City recently reduced city-wide speed from 30 MPH to 25 MPH!
Use the Systems Engineering Process to: □ Develop the operations and maintenance support applications □ Develop the pedestrian applications □ Develop the data collection applications □ Develop benefit evaluation applications

Standards Based Approach Future Interoperability & Sustainability
Focus on the standard messages for the safety applications using latest version of SAE J2735 □ Basic Safety Message (BSM) □ Signal Phase and Timing (SPaT) from the traffic controller □ Geometric information for the intersections (MAP) □ Signal Request Message (SRM) for pedestrian priority □ Signal Status Message (SSM) for interaction with the pedestrian □ Traveler Information Message (TIM) for evacuation messages Focus on SAE J2945/1 for V2V safety applications Use final versions of IEEE 1609.x as they are completed Stay with IEEE 802.11p Working with the traffic controller NTCIP updates for 1103, 1201,
1202, 1211 Stay connected with the standards programs (SAE, NTCIP, IEEE)
28 U.S. Department of Transportation
Adding project oriented data collection
Vehicles: collect the “first” and “last” SPaT message and the vehicle location from each RSE they “hear”
RSEs: collect the “first” and “last” BSM message from vehicles they “hear” Supports statistical analysis of “communications” zone around each RSE and each vehicle.
Vehicles: collect the BSM for each “new” vehicle they “hear” anywhere; Allows us to see how frequently vehicles encounter each other throughout the City.
Data containing potential PII is encrypted at the time of recording. Data recorded in-vehicle is collected by RSE at entry to garage or similar
“bottleneck” Data is sent to back office server for anonymization, analysis, and
distribution
RF Measurements
29 U.S. Department of Transportation
Adding project oriented data collection
Note on additional sensors: ASD will include accelerometers (X, Y, Z) as well as an interface to the CAN bus or OBD2 bus (steering wheel angle, brake status, heading, speed)
Vehicles continuously record (0.1 sec.) the BSM data and ASD data in a “rotating buffer”.
Whenever a configurable event occurs, the data prior to the event (for a configurable time) is stored in the ASD (pre-event data).
Following the event (for a configurable time) the same type of data is also stored (post event data)
Both are combined and encrypted into what becomes an “event” record.
Data recorded in-vehicle is collected by an RSE at entry to garage or similar “bottleneck”
The encrypted data is sent to back office server for analysis, anonymization, and aggregation – and ultimate export to USDOT
Event Data
30 U.S. Department of Transportation
Adding project oriented data collection Note on scalability:
Fleet size and backhaul bandwidth limits data collection. Not practical to collect every BSM from every active vehicle and RSE and those heard by every other active vehicle. Vehicles continuously log BSMs into their local buffer at a
configurable rate (expect 1 sec. or configurable distance, whichever is less). Data is encrypted as stored – can only be decrypted at TMC Whenever vehicle passes any RSE, the data will be uploaded to the
TMC Data at TMC will be analyzed and compared to the travel times
received from the ETC Goal: to determine if and how this data can replace the current RTMS
and ETC data
Mobility Data
All data has a limited lifespan!
31 U.S. Department of Transportation
Next Steps (CV Technology)
Using ConOps as basis for detailed system requirements □ Use Security Management and Operations Plan – inputs to SyRS □ Use Performance Management Plan – inputs to SyRS □ Use Safety Management Plan – inputs to SyRS Working with Vendors to establish parameters that can be
configured □ V2V and V2I applications Refining data analysis software to use CV data Evaluation of Driver Interface options – audio
□ Tones vs. verbal direction/alert Developing the IPv6 network support approach for NYCWiN and CV
networks

35 U.S. Department of Transportation
Ongoing Contract Work
NYCDOT is continuing to move forward with the various concept documents □ Security Management and Operations Plan □ Performance Measurement and Evaluation Plan □ Safety Management Plan □ Maintenance and Operations Plans – still in review □ Installation and testing/certification plans – will impact the SyRS
Iterating changes to the ConOps and System Requirements Specification
The ConOps is a “living document” and will be further modified and refined Review with vendors
